pounds of copper in each of February 2005,August 2005,February 2006,and August 2006.The company has decided to use the futures contracts traded in the COMEX division of the New York Mercantile Exchange to hedge its risk.One contract is for the delivery of 25,000 pounds of copper.The initial margin is $2,000 per contract and the maintenance margin is $1,500 per contract.The
company’s policy is to hedge 80% of its exposure.Contracts with maturities up to 13 months into the future are considered to have sufficient liquidity to meet the company’s needs.Devise a hedging strategy for the company.Assume the market prices (in cents per pound) today and at the future dates are as follows:
